CURRENTLY:
When a user signs up they are by default Standard.

Then, a member can navigate their way to the upgrade buttons within their profile settings and click on 'Rent' beside either Premium or Business. 

After the level is selected, they use the Chargebee portal to checkout.
Chargebee uses Stripe as the credit card processor.

The member receives a payment confirmation and shows an active trial period has started within their profile settings. However, their membership level does not change.

WHAT I WOULD LIKE:

I would like a new potential person that has not yet joined to be able to see all three levels from the first signup page, and decide in the moment what level they would like to be.

A page similar to this: https://una.io/page/hosting

Where I would layout my three options Standard, Premium, or Business.

And of course, when a member joins and starts their trial period, it properly changes their membership level.
